For my frontend reverse proxy, I have Caddy built with the Cloudflare plugin. For backend services, Caddy is configured as a web server so the static binaries suffice for those servers. In rolling out Caddy 2.4.0-RC1, I first attempted to upgrade the frontend. These are the steps I took:
Current Caddy version:(running in a FreeBSD 12.2 jail)
root@caddy:/ # caddy version
v2.4.0-beta.2 h1:DUaK4qtL3T0/gAm0fVVkHgcMN04r4zGpfPUZWHRR8QU=
Because of the issue identified in the thread Unable to build the release version of Caddy (with the Cloudflare plugin), I took a copy of the current build in case I needed to do some regression testing later.
cp /usr/local/bin/caddy /usr/local/www/caddy_2.4.0-b2
I then attempted an in situ upgrade to see if the issue identified in Caddy 2.4.0 beta 1 is now available post #17 had been resolved.
This time, Caddy wasn’t downgraded to 2.3.0, but neither was it upgraded to 2.4.0-RC1. There appeared to be no change to the built Caddy version.

At this stage, it appears I’m unable to build Caddy 2.4.0-RC1 with the Cloudflare module from the source.
